shape libraries

I have a WIP Laser Kerf Bend featurescript that's been on backburner for quite some time and I've based the implementation partially on @MichaelPascoe's Texture feature which includes a lot of pre-defined solids to choose from for pattern seeding. The way he accomplished his "library" of solids was a lot of manual…

Does anyone know the best way to access libraries of structural steel shapes?.. for example, HSS and I-beam shapes?
